Title: Improvements in or relating to Ventilation Control Apparatus
Inventor: COOKE IAN JOSEPH
IPC: G05D23/19
Filed: 1967-08-10
Abstract: 1,184,817. Automatic temperature control systems. ELECTRICITY COUNCIL. Nov. 5, 1968 [Aug.10, 1967], No.36812/67. Heading G3R. A ventilation system for an enclosure e. g. a glass house has a first sensor responsive to air temperature and a second sensor responsive to solar radiation which when the output of the second sensor exceeds that of the first in accordance with a determined relationship e. g. a differential of 5‹ C. -15‹ C. initiates operation of the ventilation system. The air sensor 12 and solar sensor 13 are connected in a bridge circuit fed from a square wave generator 14 e.g. a 10 Kc/sec transistor multi-vibrator, the points A, B, being connected through transistor amplifiers 19, 20 diode pumps 21, 22 giving opposed polarity outputs to a point C, the voltage from which is applied to a D.C. chopper amplifier and trigger circuit 25 responsive to negative signals only, which operates a reed relay 26 controlling a fan motor or a hydraulically or electrically operated ventilator mechanism, of which the latter may be moved intermittently and be provided with mercury limit switches. A bias voltage is applied to the circuit from a potentiometer 27. The sensors may be thermocouples or thermistors, preferably of identical characteristics, and when the air temperature rises above a determined level the ventilators are opened irrespective of the relative outputs of the two sensors. The first sensor is preferably enclosed in an aspirated chamber screened from sunlight and the second sensor enclosed within a non-aspirated black sphere. The arrangement is stated to be advantageous in limiting the rise of humidity and the maintenance of CO 2  content of the air when incident solar radiation is sufficient to promote photo-synthesis and transpiration in a crop in conditions of low air temperature e. g. during winter, spring and early morning of summer.
Patent GB-625297-A (GB)
Title: Method of and material for finishing metal surfaces
IPC: B05D3/10
Filed: 1946-12-13
Abstract: A coating composition for metal surfaces comprises ortho-phosphoric acid and a non-drying polar oil or fat, the ortho-phosphoric acid constituting from 1 to 15 per cent by weight of the oil or fat, the applied coating remaining in contact with the surface until the phosphoric acid content has reacted with the surface to a substantial extent.  The non-drying oil or fat may be soya bean oil or "degras," e.g. wool grease.  The composition may be applied by dipping or spraying and may be a paste, solution or emulsion.  Suitable solvents are ethyl-, propyl-, butyl- or amyl alcohol, cyclohexanol, methyl-, ethyl-, propyl ether, butyl ether of ethylene glycol, ethyl ether of propylene glycol, benzene, toluene, xylene, turpentine, pine oil, carbon tetrachloride, ethylene dichloride, tetrachlorethylene, acetone, ethyl methyl ketone.  When the composition is applied as an emulsion, an emulsifying agent such as poly-ethylene glycol esters of long chain fatty acids, e.g. sorbitan mono-oleate, or polyethylene glycol esters of alkyl substituted phenols or aliphatic amines of from 12 to 18 carbon atoms or the oleyl and stearyl esters of triethanolamine may be used.  After reaction with the surface the oil or fat may be removed by an organic solvent, e.g. ethylene trichloride, applied as a liquid or a vapour and a coating applied which may contain nitrocellulose, an alkyd resin or a urea-formaldehyde resin.  When the metal surface is to be used as a bearing element of machinery, the oil or fat may be left on the surface and acts as a lubricant for the "running in" of the surface after assembly. p  The Specification as open to inspection under Sect. 91 comprises also compositions of phosphoric acid and waxes or mineral oils. The waxes specified are petroleum wax, ozokerite and paraffin wax. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to cold pressure welding
Inventor: TINEY GEORGE THOMAS
IPC: B23K20/02
Filed: 1960-10-28
Abstract: 892,874. Welding by pressure. STANDARD TELEPHONES & CABLES Ltd. Oct. 28, 1960, No. 37139/60. Class 83 (4). In cold pressure welding metal rods or wires, the rods &c. are first abutted to effect lateral flow of metal, are parted and are then abutted again to cold pressure weld them. Apparatus for use in the welding comprises a block 2, Fig. 1, fixed in a base 1 and carrying a pair of tapered jaw halves 17, 18 in a tapered groove 5, the halves forming a bore 20 and a slot 19. Vertical pins 21 in the halves protrude into slots 6, parallel to the walls of the groove 5 and into slots 15 in lugs on a jaw retaining plate 8 urged by a spring 11 to close the jaws. A sliding block 3 carries similar jaws and is coupled by linkage to a handle 37, rotation of which causes movement of the block towards and away from block 2. In operation the plates 8 are pressed together to open the jaws and two copper wires 42, 43, Fig. 3, with trimmed ends are placed in the bores 20 projecting a little therefrom. The plates 8 are released, a lever 40 is moved between the gripped wires and the handle 37 is rotated to force the jaws against the lever to cause the jaws to grip the wires. The jaws are parted and the lever 40 is removed. The wires are then brought together and flow laterally a small amount as in Fig. 5 to form rivet heads 47, 48, but not to weld. The wires are parted, released from the jaws and repositioned therein to protrude approximately one wire diameter and are brought together again to cold weld the rivet heads. The deformed copper is removed. Rods or wire of different sizes may be so welded, the larger possibly being tapered. Specifications 689,927 and 728,139 are referred to.

Title: Crimping Yarn
Inventor: MATTINGLY DENIS ALBERT EDWARD
IPC: D02G1/12
Filed: 1966-08-19
Abstract: 1,198,992. Crimping yarn. KLINGER MFG. CO. Ltd. 21 Aug., 1967 [19 Aug., 1966], No. 37239/66. Heading D1F. A method of crimping yarn comprises feeding preheated yarn into a crimping zone in which the yarn is compressed to form a core of crimped yarn, conveying the core through a heated setting zone and passing the core to a cooling or treating zone and withdrawing the yarn from the core at a rate determined according to the automatically sensed position of the end of the core in the cooling zone. The yarn may be .preheated by being drawn between heated draw rolls or being passed in turn along the four parallel grooves of a convexly curved plate which is heated by electrical resistance wires and is heat insulated. The setting zone may be arcuate and have a toothed wheel feeding the core therethrough as in specification 1,051,721. At the end of the setting zone disengagement of the core from the wheel may be assisted by an air blast. From the setting zone the core passes along a chute into the top of a chamber in which the core piles up and into which cooling air may be directed. The chamber increases in cross-section towards the bottom thereof and it may be straight or on "J" or "U" shape. A pair of photo-cells and light sources are arranged in the inlet arm of the chamber and are connected to the motor of the drum driving the take-up package to which the yarn passes from the chamber via tensioning bars. If the pile of yarn is above the two photo-cells the package is driven at a fast speed and if below at a slow speed. The chute may be pivotally mounted and arranged to actuate a switch to stop the apparatus if due to malfunctioning the yarn in the chamber overspill and pivots the chute upwardly.
Patent GB-373220-A (GB)
Abstract: 373,220. Typewriter calculating - machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Elliott-Fisher Co. ; Cedar Street, Harrisburg, Pennsylvania, U.S.A.) Feb. 17, 1931, No. 4981. [Class 106 (i).] In a typewriter-adding machin provided with a line totalizer, one member of the usual crowding lock is replaced by a pair of separable members having between them a spreader which in its operative position prevents the depression of any numeral key. This locking occurs when the line-totalizer transfer-restoring key is depressed and also when the line-totalizer actuating wheel is moved one step beyond the lowest numeral wheel. Means are also provided for unlocking the keys if the actuating wheel is moved two steps beyond the numeral wheel. The invention is shown as applied to a machine of the Elliot-Fisher type. One member of the crowding lock 5 is replaced by a pair of members 6 which can be opened to look the keys by the turning of a shaft 8 having a flat end 7. The numeral wheels 29 of the line totalizer are actuated by a gear wheel 4 mounted on a carriage 34 moved stepwise by a controlling device 45 through a double-armed lever 31, 32. The line totalizer is so constructed that the transfer members operated while one item is being entered must be restored before a second item is entered, a key 25, shown depressed in Fig. 10, being provided for this purpose. A lever 20 having a cam slot 23 entered by a pin 24 on the key lever 25 is rocked when the key is depressed. The upper end of this lever 20 bears against the end 19 of a lever 18 connected by a link 17 to a lever 14 having a slot engaging a crank pin on the shaft 8. The keys are thus locked while the restoring lever 25 is depressed. To lock the keys when the wheel 4 moves one place beyond the line totalizer a bar 37 is secured to the carriage 34 and attached by a spring connection to a slidable plate 39 having an upturned end 41 which engages the lever 14 and operates the crowding lock. In the bar 37 is a notch 49 engaged by a spring-controlled plate 47. The plate 47 has a slot 50 in which moves the pin 24 of the restoring lever 25, the pin engaging the bottom of the slot and causing the plate 47 to be withdrawn from the notch 49 when the lever 25 nears the end of its stroke, the carriage 34 then being retracted by a spring 46. To put the line totalizer out of action the carriage is moved a second step to the right by a handle 51, the notch 49 being long enough to allow this movement. The carriage is retained in this position by a lever 52, Fig. 9, engaging another slot 53 in the bar 37 and is released by the depression of a key 55. The keys are unlocked when the carriage reaches this position by the action of a nut 42 secured to the bar 37, the nut engaging a lever 56 and causing it to swing in an anticlockwise direction so that its other end contacts with a projection of the plate 39 and pushes the latter to the left against the action of the spring 44.

Abstract: 930,170. Spark gaps. EUROPEAN ATOMIC ENERGY COMMUNITY, EURATOM. Oct. 18, 1961 [Oct. 21, 1960], No. 37408/61. Class 39 (1). A spark gap comprises two electrodes, one at least partially surrounding the other, with one or two trigger electrodes mounted in the top of the external electrode. Two such gaps are shown in Fig. 3, where the inner electrodes 6, 7 are mounted back-to-back within the outer electrodes 9, 10, which carry housings 25, 26 for the trigger electrodes, 27. The spark-gap may be used in air, in a circuit (Fig. 5, not shown) wherein a charged condenser is discharged through a magnet coil by one spark gap, and the coil then shorted a quarter oscillation later by a discharge through the second gap, producing a non-oscillatory current discharge through the magnet coil. The discharges may be triggered by releasers, Fig. 6, wherein a discharge between the electrode 47, connected to one plate 46 of a condenser, and the electrode 48, connected to the coaxial cable 30, operates the triggers 25, 26. The releasers are triggered by an impulse to the electrodes 49, the line to one releaser containing a time lag device (0-5 m.sec.).

Inventor: HARGREAVES BRIAN
IPC: D02H13/00
Filed: 1966-08-22
Abstract: 1,133,877. Stop motion for warping machines. STALWART DYEING CO. Ltd. 21 Aug., 1967 [22 Aug., 1966], No. 37547/66. Heading D1M. A detector responding to excessive tension in individual yarns of a warp consists of a comb having flexible teeth; odd-numbered teeth are electrically connected together but are insulated from the even-numbered teeth, which are also connected together. The comb is positioned so as to deflect the warp from a straight path, causing the yarns to bend all the teeth in the same direction and normally by the same amount. If the tension in one yarn is greater than in the others, it will deflect its tooth sufficiently to make contact with the next, thereby closing the stop-motion circuit.
